Hydration that goes past the surface.

Jelly-soft, weightless, gone in seconds. Skin feels soft to the touch, never sticky.

  • Jelly-soft slip, absorbs fast
  • Layers under lotion without pilling
  • Weightless, non-greasy

4 weights of hyaluronic acid

Four weights, four depths, all carried further by Mini Molecule Technology™.

  • High weight – surface hydration
  • Mid weight – mid-layer moisture
  • Low weight – deep absorption
  • Ultra-low – deepest layers

Plus 5 essential ceramides

Hydration only lasts if the barrier holds it. All five ceramides your skin makes naturally, so the moisture the HA pulls in stays put.

  • Ceramide EOP – barrier integrity and repair
  • Ceramide AP – elasticity and smoothness
  • Ceramide NP – holds moisture in, slows water loss
  • Ceramide NG + AG – lipid density and barrier cohesion

Fresh Clean scent,light enough to layer.
• Settles to skin-fresh within minutes
• Prefer none at all? Down Deep is also available fragrance-free.

Big ingredients, mini molecules.

Most body serums stop at the surface. Mini Molecule Technology™ breaks rich moisture into ultra-small molecules, sized to travel where dry skin actually needs it. Proven in independent lab testing.

  • Carried moisture up to 3x deeper than a standard lotion*
  • More hydration where dryness shows up: hands, arms, legs, neck and chest
  • Works through the layers, not just on top
*Based on independent lab skin-penetration testing vs. a standard body lotion emulsion.

Frequently asked questions

What is Mini Molecule Technology™ and how does it work?

Rich moisturizers like petrolatum are made of large molecules that sit on top of skin. Our proprietary Mini Molecule Technology™ breaks them into ultra-small molecules (under 500 Daltons) that can travel past the surface and into the layers where dryness actually starts.

Is Dewsy actually better than a standard body lotion?

In independent lab testing, Mini Molecule Technology™ carried moisture up to 3x deeper than a standard body lotion emulsion.* Most lotions are mostly water and stay on the surface; Down Deep is built to go further and last longer.

Why petrolatum, if it's known for being thick and greasy?

Because it's the gold standard for holding moisture in. The greasiness comes from its large molecules sitting on top of skin. Fluidified into mini molecules, you get the same protection with a velvety, weightless finish.

What actives are in Dewsy products?

It varies by product. Down Deep Body Lotion: 5 essential ceramides. Down Deep HA Body Serum: 4 weights of hyaluronic acid plus 5 essential ceramides. Both are carried deeper by Mini Molecule Technology™. All formulas are phthalate-free, dye-free and sulfate-free.

Is Dewsy safe for sensitive skin?

Yes. Our formulas are dermatologist-tested and tested on sensitive skin. Both Down Deep Body Lotion and Down Deep HA Body Serum are also available fragrance-free.

Should I use the serum or the lotion?

Both, if you can. Down Deep HA Body Serum goes on first to target deeper into the skin barrier; Down Deep Body Lotion goes on second to lock in moisture. Each works on its own too.

Can I get dressed right after applying?

Yes. Both formulas absorb in seconds and leave no film, so nothing sticks to your clothes.

Is Dewsy vegan and cruelty-free?

Yes. Our products are certified vegan and 100% cruelty-free.

How does Dewsy compare to drugstore therapeutic brands?

Therapeutic lotions protect the barrier well, but their large molecules sit on top, which is why they can feel heavy or greasy. Down Deep delivers the same barrier care with a weightless finish and skin that feels soft to the touch.

What our brand ambassadors are saying

  • I love the serum as it is lightweight and does not feel sticky. It does keep my skin hydrated for some time and I have noticed an overall glow!

    An Wu - @aanwu

  • The Dewsy Serum is amazing!!! It has a really lightweight, thin texture that goes on so smoothly and absorbs right into the skin. It feels super hydrating without being heavy or sticky, which I love especially living in Arizona. My skin feels soft, fresh, and moisturized after using it.

    Lauren - @laurenicole2

  • Extremely lightweight texture, a product that does so much whilst melting into your skin. It’s amazing to know how much you’re benefiting your body by using this product!

    Jess Molly Bell - @jessmollybell

  • I’ve tried so many body serums over the years, but nothing has come close to the Down Deep HA Body Serum. The hydration is next level. My skin drinks it up instantly and stays soft smooth and bouncy all day without feeling greasy. I noticed a real difference in texture within just a few uses my skin looks healthier more even and honestly just glows. It’s lightweight absorbs beautifully and layers perfectly under lotion. This has officially become a staple in my routine.

    Lilany - @lilany

  • Just because you aren’t used to putting serum on your body, let me tell you, it’s worth it! My body deserves just as much love as my face. And it absolutely shows and feels amazing when I take care of my skin. Layering the serum under the lotion locks in hydration and really adds another layer of key benefits to give my skin a smooth exterior.

Dewsy is such a standout,

"Dewsy is such a standout, the formulas feel lightweight but deeply hydrating, and my skin looks noticeably smoother and brighter after just a few uses. It gives that healthy, natural glow without feeling heavy or complicated, just really well-made skincare that actually works."

— Colleen M. (5/5)

Daily workouts, frequent sauna sessions,

"Daily workouts, frequent sauna sessions, and constant showering had left my skin dry. While I was diligent about moisturizing my face, my body often didnt get the same attention. The body lotions I've used in the past either didnt last long or felt too heavy. I started using this body serum and lotion combo a few weeks ago, and now my skin looks and feels much better. Both products apply easily and last all day while maintaining a clean, weightless finish. These have become part of my routine, and I highly recommend them."

— Tucker M. (5/5)

Finally, body care that actually goes deep!

"I've been a skincare person for years but honestly my body routine has always been an afterthought, slap on some lotion and call it a day. Dewsy completely changed that for me. The two-step system (serum first, then the lotion to seal it in) just makes sense, and you can feel the difference. My skin isnt just surface-soft anymore. . . it actually feels hydrated from within. The serum absorbs fast, no sticky residue, and the lotion locks everything in without feeling heavy. LA skin in dry weather has met its match. So happy to support this brand early, it's the real deal."
